There are around 14,000 described species of sea brush worms, of which approximately 500 are found in Swedish waters. This volume deals with the 205 species belonging to the subclass Aciculata.
Most sea brush worms are free-living, active hunters or passive sediment eaters. One of the most common active hunters is the back-bristled predatory worm, which can be found on the beaches under rocks and washed-up seaweed. Another of the sea brush worms described is the hindfoot worm, which lives in Gullmarsfjorden, the North Sea and around the British Isles, among other places. The species got its name from the large feet on the back of the body. The pinworm has crayfish and lobster as hosts and is beneficial to them by keeping the gills and eggs clean of bacteria and microalgae. There are also sea brush worms that are parasites, such as the vampire worm. It feeds by sucking blood and body fluids from its host, which is another sea brush worm. In the mouth there are many teeth that act as an anchoring device in the host animal. The volume is part of the book The National Key to Sweden's Flora and Fauna.
